If \alpha, \beta, \gamma are the roots of the equation x^3+x^2+x+1=0 then match the items of List I with those of List II List - I List - II (i) \frac{1}{\alpha}+\frac{1}{\beta}+\frac{1}{\gamma} a) -1 (ii) \alpha^3+\beta^3+\gamma^3 b) -4 (iii) \alpha^4+\beta^4+\gamma^4 c) 3 (iv) (\alpha-\beta)^2+(\beta-\gamma)^2+(\gamma-\alpha)^2 d) 3 e) 0 Then the correct match is [TG EAPCET 14 May 2023 Shift 2]

Correct Answer is : (i) → a, (ii) → a, (iii) →d, (iv) →b

(i) \to a, (ii) \to a, (iii) \to {\d}, (iv) \to {\b}

(i) \to c, (ii) \to a, (iii) \to e, (iv) \to b

(i) \to a, (ii) \to c, (iii) \to d, (iv) \to b

(i) \to c, (ii) \to a, (iii) \to b, (iv) \to e
